Thumbnail Filmstrip of PVDF Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, Clear, 100/Pk Images
Featuring a naturally hydrophilic polyvinylidene fluoride (PVDF) membrane with a 0.45um pore size, this 25mm syringe filter delivers rapid clarification of aqueous and organic solutions while minimizing sample loss. The membrane is housed in a transparent polypropylene body and configured with a Female Luer-Lok inlet and Male Luer Slip outlet for secure, leak-resistant connection to standard syringes. Supplied nonsterile in packs of 100, it provides dependable particulate removal for routine sample preparation.
Key PVDF Membrane Characteristics
- Hydrophilic structure wets out readily for fast filtration of aqueous and mixed aqueous-organic solutions.
- Low protein binding helps preserve target analytes and protein-containing samples during filtration.
- Broad chemical compatibility supports a wide range of solvents, acids, and alcohols used in analytical workflows.
- 0.45um pore size removes particulates that can plug chromatography columns and protect downstream instrumentation.
- Low extractables reduce the risk of introducing interfering background into sensitive analyses.
Key Construction Characteristics
- Housing: transparent polypropylene body that bidirectionally supports the membrane for injection or aspiration.
- Connection: Female Luer-Lok inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip).
- Operating pressure: rated for use up to 75 psi.
- Sterility and pack: nonsterile, supplied 100 per pack.
- Integrity tested construction ensures a proper filter fit and weld to eliminate potential filter bypass.
This syringe filter maintains consistent flow and reliable particulate retention across routine sample preparation, helping protect downstream columns and detectors. Low protein binding and low extractables support sample integrity for accurate, reproducible analytical results.
